What the unit for electric current
Answers
1 Ampere of current means that if you set up your chair and
stare at the electrons flowing past one point in the circuit, you'll
see 1 coulomb of charge passing that point every second.
How will you recognize 1 coulomb of charge ?
Well, every electron carries the same amount of charge, and
we know how much that is. (Read about the Millikan oil-drop
experiment in 1909.) So we know how many electrons it takes
to carry 1 coulomb of charge past the point you're watching.
All you have to do is count the electrons as they zip past.
Every time you count 6,241,509,343,000,000,000 electrons,
you can tick off 1 coulomb of total charge that they're carrying.
If you reach that count every second, you know the current
passing that point is 1 Ampere.

Answer: Option (d) is the correct answer.
Explanation:
Electronegativity is defined as the ability of an atom to gain electrons in order to become stable.
When we move downwards in a group then there will be increase in size of atom. As a result, atomic radius will also increase.
Also, due to increase in size number of electrons will increase and hence, number of protons will also increase. Therefore, atomic mass will also increase.
Thus, we can conclude that elements change as you move down a column in a periodic table as the electronegativity decreases.
* the atomic number increases
* the number of protims increases
* the atomic mass increases
* the electronegativity decreases

Answer:
work done by fuel is chemical energy and work done by moving objects is kinetic energy
Explanation:
when work is done by object that object gains energy . when the work is done by an object that object loses energy because it is transferring it to something else .
Answer:
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning

Answer : The momentum is, 357 kg.m/s
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.
Formula of momentum is:
where,
p = momentum
m = mass = 75.0 kg
v = velocity = 5.00 m/s
Now put all the given values in the above formula, we get:
Therefore. the momentum is, 357 kg.m/s
75 kg × 5 m/sec = 375 kgm/s

period of 1.262 Earth days and an orbital radius of 2.346 x 104
km. The second moon has an orbital
radius of 9.378 x 103 km.
What is the orbital period of the second moon?
Answers
same central body, the ratio of (orbital period squared) / (orbital radius cubed)
is the same number.
Moon #1: (1.262 days)² / (2.346 x 10^4 km)³
Moon #2: (orbital period)² / (9.378 x 10^3 km)³
If Kepler knew what he was talking about ... and Newton showed that he did ...
then these two fractions are equal, and may be written as a proportion.
Cross multiply the proportion:
(orbital period)² x (2.346 x 10^4)³ = (1.262 days)² x (9.378 x 10^3)³
Divide each side by (2.346 x 10^4)³:
(Orbital period)² = (1.262 days)² x (9.378 x 10^3 km)³ / (2.346 x 10^4 km)³
= 0.1017 day²
Orbital period = 0.319 Earth day = about 7.6 hours.
